Abstract
Methods and apparatus to form biocompatible energization elements are described. In some examples, the methods and apparatus to form the biocompatible energization elements involve forming pellets comprising active cathode chemistry. The active elements of the cathode and anode are sealed with a biocompatible material. In some examples, a field of use for the methods and apparatus may include any biocompatible device or product that requires energization elements.
Claims24
A method of forming a biocompatible energization element, the method comprising:
- receiving a first substrate film of a first insulating material;
- receiving a second substrate film of a second insulating material;
- cutting a first cavity in the second substrate film to form a gap spacer layer;
- cutting a second cavity in the first substrate film to form a cathode spacer layer, wherein an edge of the cavity defines a sidewall of the cavity;
- laminating a first surface of the gap spacer layer to a first surface of the cathode spacer layer;
- placing a separator into the biocompatible energization element through the first cavity in the gap spacer layer;
- receiving an anode film;
- adhering a second surface of the gap spacer layer to a first surface of the anode film;
- receiving a cathode pellet;
- and
- placing the cathode pellet into the second cavity in the cathode spacer layer, wherein the sidewall of the cavity in the cathode spacer layer and a surface of the placed separator contain the cathode pellet.
